Fig. 310.—The Sea Radish
On some coasts we find the Sweet Alyssum (Koniga maritima)—a naturalised plant with procumbent stem, narrow lanceolate, acute leaves, and white flowers. It may be recognised by its compressed, pointed pouch with one-seeded cells. This species flowers towards the end of the summer.
The Sea Radish (Raphanus maritimus) is a much larger plant, growing three or four feet in height. In common with the Wild Radish of our corn-fields, it has a tapering pod divided into one-seeded joints, but it may be distinguished from the latter by its superior height and the deeply-divided radical leaves. Its flowers are always yellow, while in the field species they may be either yellow or white; and the style is also shorter, being about the same length as the last joint of the pod.
Fig. 311.—The Sea Rocket
On sandy shores the Sea Rocket (Cakile maritima) is commonly seen, and is readily distinguished by its zigzag branches, deeply-lobed, smooth, fleshy leaves of a glaucous colour, and its succulent pod, which is divided into two one-seeded cells by a horizontal partition. It grows from one to two feet high, and bears pretty lilac flowers about midsummer.
